Wall-to-Wall
Basics
- Wall-to-wall carpets are printed either in 4 m (12 ft) or in 5 m (15 ft) width
- This product is especially popular in the contract market like hotels, restaurants, show rooms, offices, ...
- In most cases, Polyamide (Nylon) is used as face fiber. For some hospitality applications also printed wool or wool/nylon is used
Printing Methods
Printing on tufted carpet without secondary backing
- Most of the customers in Europe and the Middle East are printing on tufted carpet without secondary backing, which is applied after the printing process.
- The advantage is lower energy consumption in the steaming and drying process, and the value of the waste material is less in comparison to backed carpet.
- One disadvantage is a higher risk of bowing and skewing during handling.
- Most mats on low-pile loop carpet are printed on unbacked carpet to save money.
Printing on tufted carpet with secondary backing
- In the USA and the Far East, wall-to-wall carpets are mostly printed on already backed carpet.
- Advantage: the carpet is very stable, and bowing and skewing problems are not existing.
- Disadvantages: the secondary backing must be attached using a water-proof latex, and more energy is needed for steaming and drying.
- The line must also be designed to handle the stiffer backed carpet (accumulators instead of J-Boxes; different washing and vacuum system, longer dryer...).
